According to the Huawei documents and resources, the HLD phase is the high-level design phase of a WLAN project. It involves the following items:

Capacity planning: Determines the number and types of devices required for the WLAN network based on the customer’s requirements and network scale.

Network design: Designs the network topology, IP addressing scheme, VLAN division, security policies, and other network parameters for the WLAN network.

Deployment planning: Plans the deployment sequence, schedule, resources, and risks for the WLAN project.

AP position planning is not involved in the HLD phase. It is part of the LLD phase, which is the low-level design phase of a WLAN project. It involves the detailed design of AP positions, antenna types, channel allocation, power adjustment, and other wireless parameters for the WLAN network. Therefore, C is the correct answer.

A mesh connection can be torn down by either of the two APs that have established it by sending a Mesh Peering Close frame to the other AP. This frame indicates that the sender no longer wants to maintain the mesh connection.

When calculating the number of APs, you cannot simply divide the total required bandwidth by the maximum bandwidth of a single AP. You also need to consider other factors such as signal coverage area, user density, interference level, and application type.

Fingerprint-based positioning technology is a method that uses the signal strength or phase difference of wireless signals to locate objects. There are two types of fingerprint-based positioning technology: virtual fingerprint-based positioning and real fingerprint-based positioning. In virtual fingerprint-based positioning, the positioning engine generates a virtual fingerprint library through calculations based on the AP deployment and environment information. In real fingerprint-based positioning, the fingerprint map is obtained through onsite information collection.

B is false because only Layer 3 VXLAN gateways need to maintain VBDIF interfaces for inter-subnet communication on a VXLAN network or communication with external non-VXLAN networks. Layer 2 VXLAN gateways do not need VBDIF interfaces.

URL filtering supports four matching modes: exact matching, suffix matching, prefix matching, and keyword matching. The priority order of these modes is as follows:

Exact matching: The highest priority. An exact match means that a URL entered by a user is exactly the same as a URL in a blacklist or whitelist.

Suffix matching: The second highest priority. A suffix match means that a URL entered by a user ends with a suffix in a blacklist or whitelist.

Prefix matching: The third highest priority. A prefix match means that a URL entered by a user starts with a prefix in a blacklist or whitelist.

Keyword matching: The lowest priority. A keyword match means that a URL entered by a user contains a keyword in a blacklist or whitelist.

BSS coloring is a feature introduced in Wi-Fi 6 that assigns different colors to different BSSs to reduce co-channel interference. BSS coloring provides the following advantages:

Higher packet rate on the air interface: BSS coloring reduces collisions between packets from different BSSs on the same channel, improving packet transmission efficiency.

More efficient channel use: BSS coloring allows spatial reuse of channels by different BSSs, increasing channel utilization.

Higher concurrency in high-density scenarios: BSS coloring reduces interference among neighboring APs and improves network performance in high-density scenarios.

According to the Huawei documents and resources, 802.1X authentication using port-based access control is a method that allows only one user to access the network through a port at a time. If a user is authenticated successfully on a port, subsequent users on this port can access the network without authentication. When the authenticated user goes offline, all other users are denied access to the network1. Therefore, A is the correct answer.

The load percentage of an AP is calculated by dividing the number of associated STAs by the maximum number of STAs supported by the AP. In this case, the load percentage of AP_1 is 4/10 = 40%, and that of AP_2 is 1/10 = 10%. The load balancing mechanism needs to be enabled to balance the load between AP_1 and AP_2. Then some STAs are steered from AP_1 to AP_2 based on the load balancing threshold and the load difference threshold.
